ami madvammg of the @foggia is spparate from the rails themselves.V Said clamping ap `a,ratus in this case embodies mea f* both or clamping the frame to the rails and for advancing the two end pieces i? the frame toward each other, or Withdrawing them from each other at the proper times; The means for clamping the frame to the rails comprise, in this case, a pair 'of combined locating and Wedging devices, such as 6` here shown as shaped tgo tit the treads oi' the' rails which are illustrated as of Ythe grooved type. 'Each of these combined clamping and locating devicesis seated in a corresponding undercut'guideway, "l, in'its respective yoke` 5,5 and with each of said devices a, screw-clamp or clamps, such as 8, will usually be combined. These screwcam'ns serve to engage the under sides of "ine heads of the rails and the upper sides oit the yokes and draw the parts just described together andlocate and maintain them in proper alinement. The'vertical relation of the parts @and t relative to therails may he varied in any suitable manner, as by the insertion of thin blocks or otherwise, to regun l oradjust the vertical position of the a of the 4cutter with respect to the work. l' or tllepurpose of advancingr the rails` toward, or 'withdrawing them from, each other suitable means, such as the nuts 9, coperating with corresponding screw threads, may

be employed for moving the two ends ofthe frame and the rails clamped therein toward or away from each other lalong the guiderods By means of such, an alining and clamping apparatus as this it-Will be clear that the rails will be maintained in exact alin'ereont, with each other While they are being led during the cutting operation, and that the ends of the rails will therefore be shaped by suitable cutters to exact para? lelism.

The cutting tool of the present invention differs from that shown in the patent before .referred to mainly in having its center of rotation in a different relation with the faces to be shaped, and in beingl diilerently supp ed for operation. -The axis vof rotation, as 'will be clear by. referring to Figs. land 2, is located substantially at the center oi gravity 'ot the cross-section of the rail, this asis being indicated at 10. The cutter-*is or maywbe substantially the same as that shown in the aforesaid patent, fand is desigl noted generally by 11. As illustrated, it

comprises two parallel, lateral cutting surfaces having a ratchet-Wheel, 12, operated by a patvl and levcr,13 and 14, said lever terminating inan annular journal portion n'iounted"v on the cutter, lsubstantially centrally thereof, and journaled circumferenu 'tially in a 4bearing' in aframe member, such as 15, supported by the side pieces or guiderods ol the rail-clamping apparatus.- In

' cal.

of engage'the sides of the ring portion of theV lever and the rounded upper portion cooperates with the periphery of said annulus.

Preferably, ball-hearings, such as 17, are in" terposed betweenthes'e elements to form the' direct support for said annulus and the cutter.

The frame l5 may be of any suitable type, but one substantially like that illustrated is preferred. It is shown as having at its opposite sides two recesses for receiving the guide-rods 3--3, one of these recesses being preferably horizontal and the other vertih The former is shown at 18 and the latter at 19a This construction permits exact positioning of the tool-carrying frame in a direction transverse to the rails and. pre# -vcnts shifting of the axis of rotation 10. It also facilitates the application of the tool to the clamping apparatus and the .Work and its removal therefrom.- When in operative position the 'cutter is turned in the manner set forth in the aforesaid patent by merely -manipulating the handle 14.

`The. tool illustrated in Fig. 2 di'ers from that shown in the other views mainly in that it has gearing for actuating the outter. 'lnthe construction illustrated this gearing comprises two pairs of beVeLgearS, these gears being indicated at 20, 21, 22 and 23. `The gears 20 and22 are shown as secured to a horizontal driving spindle, 24,. while the gears 21 and 23 are secured to the upper ends ot' a pair of vertical Wormshafts, 25 .and 26, carrying Worms, 27 and 28, meshing1 with the teeth of a large gear,

29, in fixed relation with' the cutter. Power may be applied to the shaft 211 by means of a crank (not shown) or any Aother suitable Way. All of the other' parts illustrated are substantially the same as those shown in the other views and are designated by corresponding re'lerence characters.

lt will of course be obvious that any other suitable means may be employed for turning,- a cutter having its axis of rot-ation properly located in accordance with the main feature of this invention, withl respect to the center of gravityof the cross-section of the Work to be faced.

lWhat I claim is: v

1. A cutting device comprising a rotary disk having oppositely facing lateral cutting faces and la peripheral journal' surface, moans for supporting said disk peripherally'iu' turning movement, and means for imparting driving impulse to said disk. 2,'1 cutting device comprising a rotary member having oppositely facing lateral l cutting faces and a peripheral journal surlace,fmcans for supporting said member pe 16. Means for forming parallel faces 0n the abutting ends of rails to be Welded together, Comprising a rotary member, said member having at its opposite sides palllel cutting faces of a dimeter approximately equal to the height of" the rails7 means for peripherally suppozjing said annulus for turning movement about an axis passing through the aforesaid faces of the rails near the center of gravity thereof, and means for :imparting driving impulse to said annulus.

17. Means for yforming parallel faces on the abutting enlis of rails to be Welded toether com Jrisincfa rotar cutter havin at- 7 :n y u its opposite sides parallel Cutting faces, and 15, means for supporting said .cutter for rotary movement about an axis passing through the aforesaid faces of the rails and lying near the Vertical centers thereof.
